Summary & Overview
Specific developmental disorders of speech and language: ICD-10-CM Diagnosis Code Group Overview
International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM) codes under the group ICD-10-CM F80 cover specific developmental disorders of speech and language, including expressive language disorder, phonological disorder, and mixed receptive–expressive language disorder that affect communication and language development. Accurate ICD-10-CM coding of these conditions is significant for reimbursement because it ensures services are billed with diagnoses that reflect the clinical reason for therapy, influencing coverage and payment determinations.
Specific developmental disorders of speech and language Overview
This group represents delays and disorders in the acquisition and use of speech and language in children, including expressive language disorder, phonological disorder, and mixed receptive-expressive language disorder, targeting communication functions of the nervous system. These diagnoses describe developmental impairments in speech production and language comprehension that affect a child’s ability to communicate effectively. Accurate coding is important because it supports appropriate service classification and influences coverage and payment decisions tied to documented clinical needs.
Typical Clinical Scenarios
-
A 3-year-old toddler is referred by a pediatrician to a developmental-behavior clinic because of a persistent delay in combining words, limited vocabulary for age, and difficulty producing consonant sounds despite normal hearing and no cognitive impairment. Parents report the child has had these speech difficulties since first words and they interfere with intelligibility in preschool. A specific developmental speech-language disorder is assigned after speech-language evaluation rules out sensory or global developmental causes. Typical codes:
F802,F804 -
A 7-year-old school-age child is brought to a school-based speech-language pathologist for ongoing difficulties with understanding complex instructions, sentence structure, and grammatical usage that have persisted since early childhood and affect reading comprehension and academic performance. The child demonstrates normal nonverbal IQ but exhibits marked deficits in language form and use across settings; the diagnosis is applied as a chronic specific language disorder impacting educational achievement. Typical codes:
F801,F809 -
A 5-year-old with a history of autism spectrum disorder is evaluated for pronounced social communication deficits characterized by limited spontaneous speech, echolalia, and difficulty initiating conversational speech beyond what is typical for the autism symptoms. Because the speech-language impairment is distinct in its presentation and requires separate therapeutic planning, a specific developmental disorder of speech or language code is used as a comorbid diagnosis alongside the primary neurodevelopmental condition.
